Quiz zum Vortrag
What is the name of the innermost layer of all blood vessels?
- Tunica intima
- Tunica media
- Internal elastic membrane
- Tunica adventitia
- External elastic membrane
Which vessel layer is correctly paired with its descriptor?
- Adventitia - loose connective tissue that contains nerve fibers and the vasa vasorum
- Intima - all vessels have the same gene expression profile for this layer
- Media - the single layer of cells that is directly adjacent to blood flow
- Endothelium - circular muscle layer that aids in vasoconstriction
- External elastic membrane - the major muscular component of both veins and arteries
What is one of the major differences between arteries and veins seen on microscopy?
- The amount of tissue in each layer is greater in arteries.
- The capacitance of the arterial lumen is greater.
- Veins have two main layers, while arteries have three.
- The tunica media of arteries is not as well organized as the tunica media of veins.
How does the structure of the media contribute to the functions of the arterial and venous systems?
- It allows the arterial system to be a high-pressure system and the venous system to be a high-capacitance system.
- It allows the arterial system to be a low-pressure system and the venous system to be a low- capacitance system.
- It allows the arterial system to be a high-pressure system and the venous system to be a low- capacitance system.
- It allows the arterial system to be a low-pressure system and the venous system to be a high- capacitance system.
- It allows the arterial system to be a high-capacitance system and the venous system to be a high-pressure system.

The lecturer did a great job explaining the anatomy of the heart, and with ease too.
